The repurposing of former factory sites of Japan’s leading manufacturers into data center locations is gaining momentum. The appeal of these sites for data center use lies in their vast land areas and ease of securing power supply. This article introduces the specific situations of these developments.

1. Marelli

Australian real estate development giant Lendlease has entered the data center business, advancing the construction of its first data center on land acquired from auto parts manufacturer Marelli in Nisshin Town, Kita Ward, Saitama City.

Lendlease, headquartered in Australia, has bases in Asia, Europe, and North America. The current facility, their first project in the data center business, has been under construction since June 2022 on Marelli’s former factory site, approximately 33,000 square meters and about 30 kilometers from central Tokyo.

The first-phase building, a six-story structure with a total floor area of approximately 30,000 square meters, is progressing with interior construction and will have an IT load capacity of 48 megawatts. The aim is to commence operations in the fall of 2024, with plans to develop a second-phase building of a similar scale on the adjacent site.

2. Hino Motors

Hino Motors has announced plans to sell part of the land at its Hino Plant in Hino City, Tokyo, adjacent to its headquarters. The sale will involve 114,000 square meters, equivalent to one-third of the factory’s site. The company is proceeding with a designated competitive bidding process, limiting the use to data center construction.

Considering the numerous residential areas around the site, the use has been designated for data centers to minimize the impact on the living environment, with bids requested from multiple companies. Some truck parts production remains on the land to be transferred, which will be moved to the Koga Plant in Ibaraki Prefecture before the land is cleared and handed over.

Due to the impact of engine fraud, Hino Motors reported a consolidated net loss of 84.7 billion yen for the fiscal year ending March 2022. The consolidated operating profit for the fiscal year ending March 2023 is also expected to decrease by 82% year-on-year to 6 billion yen, indicating ongoing difficulties.

The purpose of the land sale is to “further stabilize the financial base through the utilization of idle assets” (according to the company).

3. Sharp

Sharp announced it has signed a basic agreement, including exclusive negotiation rights, with SoftBank for the partial sale of its Sakai Plant in Sakai City, Osaka Prefecture, where LCD production will be halted by the end of September.

SoftBank plans to build a large-scale data center for the development of generative AI (artificial intelligence) using the land and part of the building, aiming to start construction in the fall of 2024 and full-scale operations by 2025.

Regarding the utilization of the Sakai Plant site, Sharp has also agreed to start discussions with KDDI and others for establishing an AI data center. Separate negotiations will continue with SoftBank regarding a different portion of the site.

Diversification of Management Initiatives

As data center construction progresses across various locations, approaches to the theme of data centers are diversifying.

It has been reported that Japan’s NEC is considering selling its data centers. Additionally, IT infrastructure and service giant NTT Data Group announced its entry into the real estate investment trust (REIT) market focused on data centers. This marks the first establishment of a data center-focused REIT by a domestic company in Japan.

The aim is to start operations in March 2026, with an expected asset size of up to 100 billion yen. NTT Data intends to utilize this new framework to capture the rapidly increasing demand driven by AI and accelerate data center construction.

The growing importance of data centers as a management theme is becoming evident in the business reforms of major Japanese corporations. As more companies are expected to plan new initiatives, we will continue to introduce these developments.
